HOISTING AND CONVEYING APPARATUS.

To all whom it may concern."

Be'it known that. we, THOMAS SPENCER MILLER, a resident of South Ora e, and

riage and the rope':onnections therewith.

Fig. 3 is a detail view ofthe rope-drum H. Fig. 4 is a plan view of the rope-drum engine.

Fig. 5 is a detail of the friction-surfaces by which the re e-drum F is operated. Fig. 6

v is a detail the friction-surfaces b which the rope-drums E and G are operate A and B are the head and tail supports.

0 is the cable or trackway.

D D is the duplex load-carriage.

E is the friction-operated hauling-rope drum of the engine. operated thereby.

'e is the fall-rope;

F is the friction slack-pulling-rope drum of the en e.

f is t e slack-pulling rope.

G is the friction outhaul-rope drum of the,

engine. 4 v

g is the outhaul-rope extending to the tailsupport and back again and having its tail made fast to the carriage.

d is a connection between the two parts D and D of the load-carriage, which preferably consists of a ri id rod-pivotally connected at d and d with the frames of; the carriage parts, so as to constitute substantially a distance member between said carriage parts. The connections at d and d are so construct:

ed as to admit of alarge amount of playand flexibility in all lateral directions, so as to give the carriages the greatest freedom -of relative movement without permitting them to approach each other or separate.

1,. 2, and 3 are guide-sheaves on the headsupport. V

5 is the guide-sheave on the tail-su port.

7 8 and fl (Sam the wheels of the dup exloadcarriage running on the cable or trackway.

H is the load-carriage drum com osed of the plurality of parts h h h of whic preferably h and h are of equal diameter, while h is of smaller diameter.

Specification of Letters Patent. I Application filed November 14,1903. erial No. 181,203,

6 is the hauling-rope :atented. march 13, 1906.

9 is a fall-rope pilotsheave linked by the clevis 10 with the carriage part. D, so as to have feedom of movement both'longitudinally and laterally.

11 12.an d 13 14 are guide-sheaves journaled' on one side of the carriage to steady the passing run of the outhaul-rope g.

15 is the driven shaft'of the engine, which drives through the pinion 16 the spur-wheels 17 and 18, engaging by friction-clutches with the ropedrums E and G, respectively. The spur-wheel 1'8 drives the spur-wheel 19, faston the shaft 20 of rope-drum F ,Thefriction-clutch whereby the drum F is driven from the spur-wheel 19 consists of the segmental metallic friction-plates 21 and 22 of suitable composition to maintain while slipping upon each other a smooth and constant tension upon the ropes free from jerks. Agood form of construction for this friction connection is shown in Patent No. 715,111, dated December 2, 1902. The friction-clutches operating the drums E and G will be of the ordinary wood 23 and iron 24 construction shown in Fig. 6 and provided with a brake consisting of the band 30, faced with wood 31.

25 26 27 are the screws by which the pressure of thefriction-clutchesis controlled.

When a log being hauled in or lifted by the fall-rope e'", the hauling-rope e will be hauled in and the slack-pulling rope be paid out under tension by the sli ping o the surfaces 21 22. When the fa] -rope e is being carried out to take a new log, the clutch-of the drum E is released and the rope e is outhauled by the inhaul of the rope f. the duplex carriage D D is propelled toward the head-support, the ropes e and f are both:

inhauled but the speed of the drum F is suf-' ficiently in excess of E to cause more or' less slip between the surfaces 21 and 22. The weakness of the friction-clutch upon drum F as compared with that u on drum E insures that any tendency of sai two drums toward a difference in speed of inhaul shall be 'compensated for by the sli ping of said surfaces 21- and 22, so that the inhaul of the ro e f is owerless to turn the drum H against t e iniiaul of the rope e. The hauling-rope e shares in part the burden of hauling in a log withthe slack-pulling rope f. When the carriage D D is being propelled toward the tail-support by the outhaul-rope g, both the ropes e and f surfaces for the drum E at a comparative pressure which he sees 18 causing said ropes to run evenly. The distance of the pilot-hoist ing-rope sheave Qfrom the drum H is such as to give a sufliciently fair lead to the drum part h, upon which said rope is coiled. The pilot-rope sheave 9 relieves the drum H from the lateral movements that are encountered in hauling logs from various directions. Certain features herein shown and described are set forth in our still pending applications Serial No. 111,331, filed June 12, 1902, andSerial No.- 127,788, filed October 18, 1902.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. In a hauling apparatus, in combination, a cable or trackway, a carriage mounted to run thereon, a rope-drum mounted in said carriage, ropes for propelling said drum in opposite directions, stationary drums for actuating said ropes, clutches of different capabilities for actuating said drums, a fall-rope connected with the rope-drum of the carriage, and a pilot-sheave over which said fall-rope passes between the last-mentioned drum and the fall.

2. In a hauling apparatus, in combination, a traveling drum, ropes for driving said drum in opposite directions, fixed drums for actuating said ropes, a 1'0 e for connecting said traveling drum with t e object to be hauled,

and a pilot-sheave for the last-mentioned rope.

3. In a hauling apparatus, in combination, a traveling drum, two ropes for propelling the same in opposite directions, two stationary drums for actuating said ropes respectively, and two friction-clutches of dif-' ferentcapabilities for actuating said a two drums, respectively.

4. In aihaulin apparatus, in combination,

7 1 two stationary rums, a cable or trackway, a

, duplex carriage thereon, a rope-drum mounted on one part of the carriage and driven from the stationary drums, and a pilotsheave mounted on the other part of the carriage.

5. In a hauling apparatus, in combination,

I l a cable or trackway, 'a duplex carriage thereside the'carriage for driving said rope-drum in opposite directions.

7. In a hauling apparatus a duplex carriage comprising separate frames, one of said frames having a rope-drum provided with a plurality of drum-barrels of different diameters, a second of said frames being spaced apart from the drum-carrying frame, and a connection between said frames.

8. In a hauling apparatus, a duplex carriage comprising a frame having a plurality of drum-barrels of different sizes, a second frame separated from the first mentioned frame, a connection between said frames, and a swinging rope-support carried by the second frame.

9. In a hauling apparatus, in combination, a duplex carriage having a traveling drum, a rope connectin said drum with the object to be hauled, a i ot-sheave on'the carriage for said rope, an means for propelling the drum in opposite directions,

10. The combination of two carriage members spaced apart, a rope-drum carried by one of said members, two ropes for driving said drum in opposite directions, two stationary drums for actuating said ropes respectively, and a swinging sheave secured to the second of the carriage members.

11. In combination, a traveling drum, a rope operated by said drum for connection with an object to be hauled, a pilot-sheave for said rope, two ropes having their tail ends at said drum and tending to operate the same in opposite directions and two stationary drums with which the head ends of said ropes are connected. v

'12. In combination, two traveling-drum parts connected in'axial alinement, two stationary drums, a rope. connecting each of said stationary drums with one of said traveling-drum parts to operate inversely, a rope operated by said traveling drum parts for connection with an object torbe hauled, and a pilot-sheave for said last-named rope.

13. In combination, three traveling-drum ICC parts connected in axial alinement, two stationary drums, a rope connecting each of said statio'na'ry'drums to one of said drum parts to operate inversely, a rope connected with said third drum art for connection with an object to be hau ed, and a pilot-sheave for said last-namd rope.
